First Beta of Drupal 7 With SQLite Support

In this release, the database layer has been completely
rewritten, and query builders for INSERT, UPDATE, DELETE, MERGE,
and SELECT queries have all been added. The SQLite database engine
is now supported, along with master/slave replication, transactions
and multi-insert queries. Drupal 7 Beta 1 gets a new admin and
default core theme and an automated testing framework.
